The findings do not confirm consistently reduced cardiac IAcc in AN. Cardiac IAcc may change over the course of illness, with deficits potentially limited to the early stages. A major limitation of the literature concerns the almost exclusive reliance on the heartbeat counting task, the validity of which has been questioned. Future research should develop and employ alternative tasks, consider a broader conceptualization of interoception across dimensions and bodily systems, and include longitudinal investigations.
Gend et al. (Fri,) studied this question.
